INKNG ME CHANISM 'FOR PREN'ING-MACHNE S No. 921,615. SpecificationOriginal application filed June 17, 1907, Serial oi Letters Patent.

Patented May 11, 1909. Divided and this application iiled October 3,1907.

Serial No. 395,785.

To all 'whom 'it may concern:

Be it known that 1, EDWARD M. Lockwoon, of the city and county ofPhiladelphia and State of Pennsylvania, have invented an improvement innking Mechanism for Printing-Machines, of which the following is aspecification. K

Ny invention has reference to inking mechanism for'printing machines,and consists of certain improvements which are fully set forth in thefollowing specification, and shown in the accompanying drawings, whichform a part thereof.

This invention may be employed in connection with printing pressesgenerally but is more particularly useful in that type of embossing andprinting press set out in my application Serial No. 37 9,385 and iiled June 17, 1907, of which this application is a division.

The object of my invention is to provide an adjustable inking rollerwhich shall have yielding means of support for regulating the coactionof the roller with the ink supplying roller and die on type to beprinted from.

My invention consists of an inking roller combined with means for givingto it a reciprocating movement over the carriage and the die or ty ethereon, spring controlled devices for pressing the inking roller towardthe die or type, and hand controlled devices for regulating'the springcontrolled devices whereby the roller may be adjusted normally tovaryits elevation with respect to the carriage upon which the die ortype is clamped.

My invention also embodies details of construction which, together withlthe features above specified, will be better understood by reference tothe drawings, in which :f

Figure 1 is a side elevation of an embossing and printing pressembodying my improvements; Fig. 2 is an elevation of the ink applyingroller and its supporting devices; Fig. 3 is a side elevation of thesame; Fig. 4 is a sectional elevation of a portion of the same; andFigs. 5 and 0 are pla-n views of details of the same.

2 is the main frame of the press, 3 are the guides for the reciprocatingcarriage Li, which carries the embossing and printing die or type. Thiscarriage is reciprocated in its guides by links 6 and 7,

jointed at 3.l

` applying The link G is connected to the rocking lever 5, which isrocked by link S1, rocker arm S0 and rock shaft 7 9, the latter beingrocked by arm S0 and connecting rod 8S which receives its reciprocatingmotion from a crank wheel 86 and power shaft 21. The hinge between theparts G and 7 is provided with a guide roller S which travels in guides9 and 10 in the main frame'and gives to the carriage a dwell in itsmotion when it reaches the print-ing position.

13 is the embossing plunger and is intended to carry the die to give theimpression in the act of embossing and printing, and may be reciprocatedin any suitable mann r.

Then the carriage et with the die clamp thereon is moved backward, theink is applied to the surface of the die by means of the ink applyingroller 31 which is preferably'made with a plush surface, so that the inkmay enter the recesses in the die. This ink applying roller receives theink from a rotating ink roller 30 revolving in an ink well, it beingdriven by means of a sprocket wheel 67 and a sprocket chain G6 receivingpower from a sprocket wheel G5 on the driving shaft (ist, as shown inFig. 1. The ink roller 31 is flexibly carried on the upper end of therocker arms 32, and these are rocked by links 33,bell cranks 34, rod 35,and cam 30 which is secured to thc cani shaft 21. This cam is so timedas to its ac tion that the ink applying roller 31 has been moved forwardand held. stationary at the time the carriage 4 is being moved back wardand forward under it.

Referring now to the means supporting the inking roller 31, l willrefermore specifically to 2 to t3. The shaft 102 is loosely jonrnaled in theends of the rocking arms Secured to this shaft 102 is an arm 103 havinga hole near its end. Extending through this hole is a screwthreaded rod105 which screws into a pivoted nut 32LL on one of the arms 32. Rod 105is provided with a rigid collar 100 againstwhich the arm 103 rests andupon which it is spring pressed by a coiled spring 10st on the upperextension of the screw-threaded rod 105. By turning the rod 105 it isscrewed into the nut 32a and therefore will cause the shaft 102 to takedifferent posilock the rod 105 for flexibly tions of adpistment. To

Y these arms are each clamp 11 of the car iage l so against accidentalunscrewing, l provide a collar 107- having' one or more teeth 107a whichmay engage one or more of the rethermore is carried on the rod by aspline connection, so that it does not turn on the rod, but will rotatewith it and has capacity j for longitudinal adjustment. I Secured to theshaft 102 are arms 117, and j provided with lateral j projecting pins1171. Loosely sleeved upon j the shaft 102 are two bearings 109 which jare provided with transverse apertures 114 l into which the lateral pins117il extend with j freedom of considerable motion (Fig. L1). Plungers115 carried by `the bearings 109 are spring pressed upward by springs116 so as to malte a spring' support against downward thrust by the pins11721. The bearings 109 have notches 110 for receiving the ends'of theshaft 31a carrying the inlring roller 31. The shaft 31il is locked inposition in the bearings 109 by spring bolts 111 which are presseddownward by coiled springs 112. A hand nut 113 is secured to the upperend of each bolt for raising it against the action of the spring whenrej leasing' the shaft. Pins 1133' are secured to the nuts 113 so thatwhen the bolts are fully I raised and slightly turned, they are held in,l such elevated position as will permit the shaft to be readilywithdrawn. Furtherj more, when the bolts are in locking position, tiepins 113a are received in grooves 113b wnich prevent the bolts fromturning and thereby maintain the flat side of the bolts presented to theshaft 31a, as will be readl ily understood from Fig. l. It will now be lunderstood that if a pressure is applied to the roller 31 upward, thebearings 109 will rock upon the shaft 102 and this upward l movementwill be iesisted by the coiled! and hence will be any level orirregularity in the surface of the die to which it is applying ink.Moreover, the normal level of this inking roller is readily adjusted bythe screw adjusts the shaft 102 and t iereby changes the normal positionof the bearings 109 with relation to the level of the die carriage.lVheels 118 may be secured to the shaft 31El for the purpose of engagingthe wheels 11'Cl on the side of the die that the inling roller 31 willbe elevated until it gets over the rear end of the die clamp and willthen be lowered into inlring conta and again elevated forward part ofthe die clamp, and vice versa. In this way, the ink is thoroughlyapplied to the die and not to any other part of the machine. Theflexible supporting of the inking roller combined with the means forrelatively adjusting its dist-ance with rej transverse shaft spect tothe die carrying' carriage which I have here shown and ingly effective,but it is evident that the particular adjustments involved may besecured in many other modified forms of apparatus. While l have shownthe details of construction which 1 have preferred and employed in thecommercial form of press embodying my improvementsl do not confinemyself to these specific details, as it is evident to one skilled in theart that the same general adjustments may be accomplished by other formsof the said details parting from the spirit of the invent-ion involvedin them.
